Ulster Bank will today be urged to postpone all branch closures until 2023.
It will appear before the Oireachtas finance committee to explain why it's leaving the Irish market on a phased basis after 160 years.
The organisation announced the move on Friday, in a major blow to its 2,800 staff here.
John O'Connell, from the Financial Services Union, will also attend the committee meeting today - he wants clarity from Ulster Bank.
"For us there's three key principles that we want to enshrine with the committee today, and that is there should be no compulsory redundancies, that branch closures should be paused until the end of 2022, and that jobs must follow the work.
"All the engagement must be on securing the maximum amount of jobs out of this situation."
